Abstract:
We report on measurements of differential cross sections d sigma /dpT
for prompt charm meson production in pp-bar collisions at sqrt[s]=1.96
TeV using 5.8±0.3 pb-1 of data from the CDF II detector at the Fermilab
Tevatron. The data are collected with a new trigger that is sensitive to
the long lifetime of hadrons containing heavy flavor. The charm meson
cross sections are measured in the central rapidity region |y| K- pi +, D*+-->D0 pi +,
D+-->K- pi + pi +, D+s--> phi pi +, and their charge conjugates. The
measured cross sections are compared to theoretical calculations.
